FAQ

Will this valve fit a Hemi head?

Do I need to replace my valve guides?

No. This valve features a 6.5mm stem, allowing it to fit stock valve guides. The tip is undercut to 6mm to work with EC 6mm valve retainers.


What retainers are compatible with this valve?

Use EC 6mm valve retainers to ensure proper fitment and secure valve operation. Other retainers may not fit the undercut tip correctly.


Is this valve longer than stock?
